Basics! Definitions! Demo!

FROM ubuntu

RUN apt-get install -y software-properties-common python
RUN add-apt-repository ppa:chris-lea/node.js

CMD ["/usr/bin/node", "/var/www/app.js"] 

Let's set some expectations

Docker helps developers 

by providing solutions for

 

  • "It works on my machine"
  • Simpler and faster (and automated) Deployments  
  • Dependency Management 
  • Quicker technological improvements
  • Reproducibility of environment (process)
    • By keeping the environment..

.... hahaha ...

Docker helps sys admins

by providing ways to handle

  • "It worked on my machine..."
  • Managing environment changes
  • Conflicting runtimes 
  • Log files and monitoring
  • Reduction in complexity 
  • "Runs Anywhere"

Docker - 

The Big Picture

  • Ridiculous growth
  • Open source engine
  • Linux (and maybe? windows)
  • Allows to create and share images
  • Standard format

Demo

  • Show you docker daemon on AWS
  • Show you a Docker File (which is a DSL)
  • Deploy simple HTML/JS/CSS application 
  • Make change and redeploy 

DevOps

and 

Containerization 

Docker 

Docker will be one of many tools that will support cloud initiative at CU / VMIT

Local, Hybrid,  Campus, AWS, Azure

 Dev Principals in 2015
